I'm not aware of a Juniper switch as modular as the 4900M, but I'm sure
someone will correct me if I'm wrong.  I think you have to make some
sacrifices with the cisco box though.  For example when you use the twingig
modules in the 10G slot you sacrifice alot of buffer space.  I think the EX
is a little cheaper depending on your relationship with juniper, it's also
stackable.  You just have to decide if it fits your needs though.

The MX80 is more of a ethernet router.  If you don't need the advanced
routing or the port density you'll probably end up spending too much.

agree.  The 3200 would work too, but I've never deployed one.  I almost
always want a VC.
